Be'itknown that I,ERN s'r 1 a citizen of the'United'States, and residentof Dorchester, in thecounty of Suffolk and State of Massachusetts, haveinvented certain' newand useful Improvements in Organ-Pipes, of whichthefollowing is a specification.-

The present pipes and its main object'isto produce, a

pipe which-will speak with the characteristic tonelof a French horn. Ihave accomplished this object by making certain modifications in andadditions to the standard reed plpe,

which I will now describe and hereinafter I claim.

.drawings in which The features in which my invention co'n-v sists areillustrated in the accompanying Figure lis an elevationof a reed pipeembodying my invention, the upper end of which is shown broken away.-Fig. 2 1s an elevation as seen from the right of Fig. 1 of the upper endof my improved organ pipe. Fig. Sis a longitudinal section on line-33 ofFig. 1, on an enlarged scale, representing the interior construction ofthe foot and shallot. Fig; 4: is a sectional viewof the mouthpiece'on aplane atright angles to that of the line 3+3, and showing the shallotinelevation as viewed from the leftof Fig: 3, the tongue and tuning wirebeing omitted. I Like reference characters designate the Y same parts inall the figures,

In the drawings a'represents thefoot, b the body, 0 the shallot or reed,d the, tongue,

and e the tuning wire ofan organpipe of I bination, hereinafterdescribed is preserved;

the'reed type. The foot and body are or may be constructed and connectedtogether in the manner usual with pipes of this type,

theymay be made in any other metal or ma- 7 terial whatever suitable forthe purpose. The foot has the usual opening fat one end, while itsopposite end is stopped by a plug or a block 9* having a centralpassageway into one end of which the small end of the bodyis inserted,and into the opposite'end of which, and within the foot is inserted theopen endof the shallot. The latter is secured in the plug and the,tongue is likewise secured so asito extend over the opening h" in theside of the shallot, by means of a wedge i in the usual manner. The.tuning s a-amal am rfttisrat liy invention rel-ates. to organ vibratingperiodof the tongue, the vibrating Minimum filed'mmh 263915;: SeriaI No.17,153.

1 fraaaaaraaiea I The improvements which I have -made, 7

by which I have secured radically new effects in the qualityjof toneproduced by the pipe consist of the following; The shallot is made withgreater than ordinary length I and is extended below the lowerendof theopening it, thus forming a pocket j below said opening, -suchpocket orcourse being closed at the bottom end of the shallot. The top of thebody tube is closed or covered by. an end wall Jr}, thus providing apocket Z in said body. In one sideof the pocketl is .a tuning slito'adjacent to which "is the tuning flap or tongue 70. The function ofthe vibrating period of the, column of air in the body it intosynchronism with the length of which latter, and by consequence thistuning slit and tuning flap is to bring the pitch of the pipe, beingcontrolled by the tuning wire e. I a p I I have found that pipesconstructed with the novel features above described, that is combiningapocket in the shallot ofthe pipe below the reed, with a pocket in thetop end of the body, simulate exactly the characteristic tone of theFrench horn.

Thev drawings here presented to illustrate as limiting the invention .tothe particular 'of thepipe,either as to'its body and foot or theforegoing. description are not to be taken form 'of reed pipe shown, oras excluding its shallot and tongue, provided the com j I Where in theforegoingdescription and the" following claims I have used the wordsabove, below, top,, bottom, or words of similar meanings I have,intended vsuch words to refer to the position inwhich the pipe is shownin the drawing and to that in l which it is usually placed, and withoutany intention of limitingthe location or position in "whichta .pipeembodying the invention upperend, in combination with a shallot I havinga pocket in its lower end.
